Abstract: 299,474. Pivert, L. J. Oct. 27, 1927, [Convention date]. Two-part couplings. - A radio receiving-set designed to receive from a number of transmitting stations without dial adjustments comprises a number of coils, capacities, and resistances which are selected or adjusted, to render the set responsive to a particular transmitter, by the insertion into a socket on the set of a plug appropriate to the particular transmitter. Fig. 1 shows the set diagrammatically, and Figs. 2-4 show different forms of selecting plugs. The set may comprise three sets of coils, the primary tuning coils 3 - - 6, aerial coils 15 - - 18, and secondary tuning coils 30 - - 33. One end of each coil is brought to a contact member situated on the walls of a socket X in the set. The movable plates 12, 27 of the primary and secondary tuning-condensers are connected to arms 14, 28 which are pivoted at 13, 29 so that the movable plates may be adjusted relatively to the fixed plates 11, 26. The ends of the arms 14, 28 project into the socket space X. In addition a rheostat 23 and a potentiometer 24 are exposed in one of the walls of the socket. The selecting-plug, Fig. 2, has contact members 41, 42, 43 on its side walls for selecting a particular coil from each set, and contacts 39, 40 for engaging the rheostat 23 and potentiometer 24. It also carries two pins 44, 45 which pass through nuts 44', 45' and can be preliminarily adjusted by knobs 46, 47. On insertion of the plug, the pins engage the arms 14, 28 and adjust the tuning-condensers to suit the desired transmitting station. One plug may be provided for each desired transmitter, or the plugs may be constructed of star shape, or polygonal cross section, Figs. 3 and 4, with multiple contacts on each face, so that different stations may be selected by inserting the plug in different angular positions, or to different depths.

Abstract: 806,794. Gas turbine plant. TECHNISCHE STUDIEN A.G., FUR. Oct. 12, 1956 [Oct. 12, 1955], No. 31156/56. Class 110 (3). Gaseous working medium is compressed in at least one compressor and, after being heated, is expanded in a turbine driving the compressor and a variable-speed output turbine having at least one stage traversed radially inwardly, the output turbine being in parallel with at least one stage of the turbine driving the compressor. In the closed-circuit plant shown, the working medium is compressed by a compressor 1 and passes in succession through a preheater 2 in which it is heated by turbine exhaust, a heatexchanger 3 in which it is further heated by the combustion of fuel supplied through a line 7, and a turbine 4 which drives the compressor, returning to the compressor by way of the preheater 2 and a heat-exchanger 6 in which is cooled by water. The medium also passes through useful-output turbine 5, which is connected in parallel either with the whole of the turbine 4 or with part of it, preferably the output stage, as shown. The turbine 5 is of radiallyinward-flow type, and drives a variable-speed load such as a ship propeller 11, reversing being effected by adjustable inlet guide blades. There may be additional radial-flow or axial-flow stages. The power output and speed of the turbine 5 can be increased by supplying additional working medium to the circuit from a reservoir 12, thereby increasing the density and pressure of the medium. The power output and speed of the turbine 4 also rise, to provide the necessary increase in the compression ratio of the compressor 1.

Abstract: 947,510. Rolling; producing metal tubes. BENTHAM BROS. & CO. Ltd. Sept. 3, 1962 [Sept. 2, 1961], No. 31629/61. Headings B3A and B3M. A method of producing metal tubes having an axial or helical welded seam includes the step of cold rolling at least the weld of the tube in such a manner that the tube is freed from its supporting mandrel to allow removal of the tube. A tube 40 is mounted on a mandrel 23 rotatably supported between two generally A- shaped frames 10. A carriage 14 which runs along a beam 13 between the frames carries a roll 19 which is pivoted to an arm 18 and urged against the tube by a pneumatic cylinder assembly 20. The carriage is driven by a chain 31 carried on a sprocket 30, a pneumatic cylinder assembly 28 driving the sprocket 30 by means of a further chain and gearing to shift the carriage. The direction of travel of the carriage is automatically reversed by actuation of a switch 35 by arms on a further sprocket. For helically-welded tubes the tube and mandrel are rotated during rolling. Collars 41 on the mandrel prevent unwanted distortion of the tube ends during rolling. The roll 19 may have the profile shown or be barrel shaped, and two or more rolls may be used.

Title: Improvements in or relating to motor vehicle transmissions
IPC: F16H47/04
Filed: 1956-10-18
Abstract: 803,228. Variable-speed gearing. FORD MOTOR CO., Ltd. Oct. 18, 1956 [Nov. 8, 1955], No. 31705/56. Class 80 (2). The output shaft 14 of a vehicle transmission gear is driven from the engine shaft 13 through an epicyclic gear 48 associated with a pair of variable displacement hydraulic units A, B, which are interconnected by manifolds 33, 34. The arrangement gives a continuously variable speed to the shaft 14 from reverse through neutral to forward. The hydraulic units have ball pistons 32 slidable in radial cylinders 31 in rotors 29, 30 which are rotatable on a central sleeve 36 concentric with a shaft 37 connected to the driving shaft 13 by a flexible coupling 39. Surrounding each set of ball pistons 32 is a cylindrical body 26 having diametrically aligned pistons 27, 28 reciprocal in cylinder portions 23, 24 of a fixed casing. The eccentricity of the members 26 and thus the stroke of the pistons 32 can thus be varied. The rotor 29, unit A, is fixed to the shaft 37 by a flange 42 and the rotor 30, unit B, is fixed by a hub 51 to a sun gear 49 free on the shaft 14. The hub 51 drives an hydraulic pump 52. A planet carrier 53 is fixed to the shaft 14 and a ring gear 47 to the shaft 37. The output shaft 14 drives an hydraulic pump 58. In operation neutral is obtained by adjusting the units A, B so that the sun gear 49 is rotated backwardly relatively to the ring gear 47 so that the planet carrier 52 and driven shaft 14 are stationary. Increasing the backward speed of the sun 49 gives a reverse drive to the shaft 14. Decreasing the backward speed of the sun 49 gives a low forward drive to shaft 14. When the sun 49 becomes stationary a wholly mechanical drive is obtained. Forward rotation of the sun 49 increases the forward speed of the driven shaft. Hydraulic unit A is controlled by a valve A<SP>1</SP> associated with passages 63, 64, leading to the cylinders 23, 24. The valve A<SP>1</SP> is acted on by a lever 67 connected to the accelerator pedal, a tension spring 66, the pressure in the manifold 33 and by throttled and non-throttled pressures derived by the pump 58. The valve B<SP>1</SP> controlling the unit B is acted upon by a manual lever 88, compression spring 87, pressures in manifolds 33, 34, throttled and non-throttled pressures derived by the pump 52 and the non-throttled pressure of the pump 58. In operation manipulation of the levers 67, 88 will give the desired speed condition.
